DIY Mini Quad MultiWii ESC Calibration

Please help us to find bad videos. Broken or unappropriated video content?

Thanks to all who suggested the MultiWii ESC calibration tip. I had originally done a manual calibration of each ESC, but this all-in-one process appeared to yield better results. I think where I stand now is one of the motors is faulty. Instead of messing around with it I ordered some new Turnigy 1811-2900kV motors to test them out. I'm printing a new frame and will give them a try. This Mini Quad will be in the air soon thanks to all of your suggestions and feedback!
Here is the link to the MultiWii ESC calibration process that I go through in the video:
